Sharing with Pinterest button has broken image

I recently have run into all images when shared with the Pinterest sharing button have a broken image. It used to work OK and there are a few things I suspect.

I’ve disabled ALL plugins down to just Jetpack and also changed my theme from my child theme to a freshly downloaded twenty fifteen theme and it doesn’t change anything.

What I suspect is that it stopped working when I changed my entire website over to ssl but I have no proof of that.
